Technical field：
The utility model is related to boring machine fields, are specifically related to a kind of mobile boring being suitble to the small-sized interior hole machined in scene
Bed.
Background technology：
Boring machine traditional at present is mounted on ground, is secured the workpiece against on boring machine, and main axis drives workpiece rotation,
Knife rest is axially or radially moved along workpiece, and the cutter being mounted on knife rest carries out machining, this boring to inner hole of workpiece
Bed is suitble to the processing of moveable middle-size and small-size part.But in enterprises such as chemical plant, shipyard, steel plant, some workpiece are very huge
And heaviness, dismounting is very difficult, can cause great transportation cost, re-assembly and waste a large amount of man power and material.And have
Workpiece cannot be unloaded from equipment, be processed so these workpiece can not be installed on traditional boring machine.
Invention content：
It is small the technical problem to be solved by the utility model is to provide a kind of movement is easy for installation, it is suitably adapted for existing
The mobile boring machine of the small-sized interior hole machined in field.
What above-mentioned purpose was realized in：It includes feed bracket, and the first AC servo motor is in feed bracket, silk
The rear end of thick stick is equipped with gear, and the gear on the first AC servo motor output shaft is engaged with the gear of leading screw rear end, before leading screw
End bearing and locking nut are connect with fixing bracket, are moved holder and are equipped with the screw coordinated with leading screw, move on holder
Screw is installed with leading screw cooperation；
Further include the second AC servo motor, the second AC servo motor is connected with servo planetary reducer, servo planet
The output shaft of speed reducer and the rear end of boring bar are connected by connector sleeve, and servo planetary reducer is connected by flange and mobile holder
It connects；
It is set with rear copper sheathing, rear copper sheathing and boring bar sliding contact in the middle part of boring bar, rear flange, rear copper sheathing are equipped with outside rear copper sheathing
It is fixed together with rear flange, rear flange is connected with fixing bracket, and the front end sleeve of boring bar is equipped with preceding copper sheathing, and preceding copper sheathing is slided with boring bar
Dynamic contact, preceding copper sheathing outside are equipped with forward flange.
Centring sleeve is equipped on boring bar between forward flange and rear flange, the centring sleeve is taper, the centering
Set is two-half structure, i.e. centring sleeve is bolted together by two centring sleeve monomer compositions, two centring sleeve monomers.
Centring sleeve is selected according to the diameter of multiple holes to be repaired, so that centring sleeve is contacted with hole wall, can determine the position of boring bar in this way.
The rear end of the leading screw is stretched out from feed bracket, and leading screw is equipped with handwheel from the part that feed bracket is stretched out, and is used for
The amount of feeding is adjusted manually.
The utility model has the advantages that：When work, forward flange and rear flange are all fixed in repaiied equipment, unload centering
Set, the work of the second AC servo motor can drive boring bar to rotate, the work of the first AC servo motor, and boring is driven by mobile holder
Bar is moved forward and backward, to complete the reparation to endoporus.Its conveniently moving, it is small, it is not necessarily to detaching equipment when use, improves and repairs
Speed reduces rehabilitation cost, repairs precision height, can guarantee that former and later two holes are concentric when repairing former and later two holes.Utilize the present apparatus
It can be processed at the scene, the bore hole base part of especially live Bead weld repair is easy to use such as the endoporus of large size bearing seat.
